Jamesbrittenia plant named ‘DANBRIT4’

ABSTRACT

A new and distinct  Jamesbrittenia  plant named ‘DANBRIT4’ characterized by having 5-petalled flowers, measuring about 2.0 cm in diameter, with orange-red petals and corolla which is green-yellow at throat and orange at center; vigorous growth habit, which maintains a trailing, compact growth habit; early flowering response; and suitable for use with hanging basket planters, combination planters and ground cover under full sunlight and slight shade.

Latin name of the genus and species of the claimed plant: Jamesbrittenia sp.

Variety denomination: ‘DANBRIT4’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Jamesbrittenia plant, botanically known as Jamesbrittenia hybrida of the Scrophulariaceae family, and is hereinafter referred to by the cultivar name ‘DANBRIT4’.

The new Jamesbrittenia cultivar is a product of a controlled breeding program conducted by the inventor, Gabriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to develop a new Jamesbrittenia cultivar with large, orange-red flowers and trailing, compact growth habit.

The new Jamesbrittenia cultivar originated from open pollination of the female or seed parent, Jamesbrittenia sp. ‘ST-4-250’ (unpatented), by the inventor, Gabriel Danziger, in 2004 in Moshav Mishmar Hashiva, Israel. The new Jamesbrittenia cultivar was discovered and selected by the inventor, Gabriel Danziger, as a single flowering plant within the progeny of the stated cross in a controlled environment in 2005 in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new Jamesbrittenia cultivar by vegetative tip cuttings was first performed in March of 2005 in Moshav Mishmar Hashiva, Israel, and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘DANBRIT4’, which in combination distinguish this Jamesbrittenia as a new and distinct cultivar:

-   -   1. 5-petalled flowers, measuring about 2.0 cm in diameter, with         orange-red petals and corolla which is green-yellow at throat         and orange at center;     -   2. Vigorous growth, which maintains a trailing, compact growth         habit;     -   3. Early flowering response; and     -   4. Suitable for use with hanging basket planters, combination         planters and ground cover under full sunlight and slight shade.

Plants of ‘DANBRIT4’ differ from the plants of the female parental cultivar in the characteristics described in Table 1:

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new Jamesbrittenia ‘DANBRIT4’ is Jamesbrittenia ‘Breeze Upright White’, Balbreupit (U.S. Pat. No. 14,372). In side-by-side comparisons conducted in Moshav Mishmar Hashiva, Israel, plants of the new Jamesbrittenia ‘DANBRIT4’ differed from plants of Jamesbrittenia ‘Breeze Upright White’ in the characteristics described in Table 2:

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Jamesbrittenia ‘DANBRIT4’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the color of ‘DANBRIT4’.

FIG. 1 shows a side view perspective a typical flowering plant of ‘DANBRIT4’ in a hanging planter, at 3 months of age.

FIG. 2 shows a close-up view of flowers and buds of a typical flowering plant of ‘DANBRIT4’, at 3 months of age.

DETAILED BOTANICAL DESCRIPTION

The new Jamesbrittenia cultivar ‘DANBRIT4’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.

The aforementioned photographs, together with the following observations, measurements and values describe the new Jamesbrittenia cultivar as grown in a greenhouse in Moshav Mishmar Hashiva, Israel, under conditions which closely approximate those generally used in commercial practice. Greenhouse temperature averages 18° C. at night and 24° C. day. Constant fertilization with a balanced NPK fertilizer at 200 ppm N level and that contains average levels of micronutrients with a slightly increased levels of iron should be used when growing ‘DANBRIT4’.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), 2001 edition, except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately 12:00 noon in Moshav Mishmar Hashiva, Israel. The age of the plant described is 3 months.
